Earlier, 10:11 p.m.: Indianapolis Metropolitan Police have a suspect in custody in connection with the killing of a woman in a Downtown apartment building, the department announced Friday night.

Officers found the woman's body shortly before 6:30 a.m. in the second floor of the gym at the 9 On Canal Apartments, 335 W. 9th St., Indianapolis Metropolitan Police Department Sgt. Kendale Adams said.

Police believe the woman was exercising in the fitness center when she was attacked. As of Friday night, police said they were not searching for additional suspects.

"There are certain areas of the building that are secured by key card," he said, "but some of those areas are on a timed-release lock."

"I think our detectives feel confident in the video and the information they have received so far," Adams said.

Police released surveillance footage Friday afternoon of a man considered to be a person of interest in the case.
